  • Publication number: 20110294362
    Abstract: In one embodiment of the present invention, there is provided an electrical connector comprising an insulative housing having a longitudinal base with a first side and a second side. Extending from the base at the first side is a tongue portion having a first tongue section and a second tongue section, both sections having a first face and a second face. A plurality of passageways are defined on the first faces of both sections. Each of the passageways has a recess located at one end and a plurality of conductive contacts are received in the passageways. Each contact comprises a mating section, a mounting section and a retainer section bridging the mating section to the mounting section whereby the mating section of the contact is free to flex into the recess. In another embodiment of the present invention, there is provided an electrical connector having a socket extending from the base at the second side.

  • Patent number: 7094075
    Abstract: A connector for mounting on a printed wiring board includes a housing, contact terminals disposed in the housing, a fixing member, and a hood detachably connected to the housing with the fixing member. The contact terminals each have a contact pin to contact a mating connector and a terminal portion to contact a wiring pattern on the printed wiring board. The hood includes a protruding portion having an insertion hole, whereas the housing includes a cavity to accommodate the protruding portion and a vertical hole, with which the insertion hole is communicated when the protruding portion is accommodated in the cavity. The fixing member includes a projected rod. The projected rod is inserted into the vertical hole and the insertion hole, thereby allowing the hood to be detachably attached to the housing.
